To provide a packaging material, corrugated board base paper, and corrugated board suitable for use in a method for refrigerating and preserving food in an electric field atmosphere.SOLUTION: This invention is related to a packaging material for a storage cabinet in which an electric field atmosphere exists, and the packaging material has a surface resistivity of 0.1 to 100 ten thousand Ω/Sq measured in accordance with JIS K 6271. The corrugated board base paper is composed of a plurality of layers of base paper, and at least one layer of the base paper is composed of the packaging material. The corrugated board is formed by laminating at least front base paper and rear base paper, and a conductive coating agent is applied to the rear surface of the front base paper and a moisture-proof performance imparting agent is applied to the surface of the rear base paper.SELECTED DRAWING: Figure 1 【課題】電場雰囲気で食品を冷蔵保存する方法に適する包装材、段ボール原紙、及び段ボールを提供する。【解決手段】電場雰囲気が存在する保存庫用の包装材であり、ＪＩＳ Ｋ ６２７１に準拠して測定した表面抵抗率が０．１〜１００万Ω／Ｓｑである。段ボール原紙は、複数層の原紙で構成され、少なくともいずれか一層の前記原紙が上記包装材で構成されている。少なくとも表原紙及び裏原紙が積層されて形成されている段ボールであり、表原紙の裏面に導電性塗工剤が塗布され、かつ裏原紙の表面に防湿性能付与剤が塗布されている。【選択図】図１
